Pain is the most common symptom of sinusitis. You have several different sinuses above and below your eyes as well as behind your nose. Any of these can hurt when you have a sinus infection. Inflammation and swelling cause your sinuses to ache with a dull pressure. You may feel pain in your forehead, on either side of your nose, in your upper jaws and teeth, or between your eyes. This may lead to a headache (see below).
Sinus infections usually begin with the symptoms of a cold (for example, a runny nose, occasional cough and/or mild fever), and then develop into pain and pressure in the sinus cavities. About 7 to 10 days after initial cold-like symptoms other symptoms develop that suggest you may have a sinus infection. Sinus infection symptoms include. 1  a yellowish-greenish nasal discharge that may have an odor, 2  bad breath, 3  puffiness around the eyes, 4  headaches, 5  pressure in the sinuses, and. 6  coughing.
